Description

Technical Field

[0001] This invention relates to the field of rock mass prevention and control technology, specifically to a method for designing anchors for irregular boundary slopes based on topological relationships. Background Technology

[0002] In the process of infrastructure construction, the excavation, slope trimming, and filling of mountains inevitably involve encountering naturally or artificially formed slopes, which are a common engineering geological environment in engineering construction. The stability of slopes directly determines the site selection of engineering projects and has a decisive impact on the stability and suitability of future engineering projects. Because a certain range of weak structural planes are formed between the slope and the rock strata, the slope is prone to relative displacement along the weak structural planes existing within the rock mass. In order to meet the needs of production and construction, slope support and reinforcement design is often required to provide a good geological environment for engineering site construction and ensure the safe and stable operation of engineering projects within the site.

[0003] In the process of slope support and reinforcement design, common methods include laying steel mesh on the slope surface, using mesh-hanging shotcrete, inserting anchor rods and anchor cables inside the slope, and setting up pile-anchor support structures and drainage holes. Before carrying out construction measures, it is necessary to design the layout of the slope reinforcement components.

[0004] Chinese Patent Publication No. CN117344590A discloses a method and structure for constructing an erosion-resistant roadbed. This invention uses a rib-column retaining wall composed of ribs and retaining plates to form the basic structure of the roadbed with the slope. Anchors are installed through pre-reserved anchor holes on the ribs, and the column structure effectively reduces the scouring effect of water flow. However, this invention makes it difficult to coordinate the arrangement of various types of anchors on the same slope reinforcement surface, which makes it difficult to avoid conflicts in the arrangement of reinforcement components and leads to low design efficiency. At the same time, the actual three-dimensional slope surface is often irregular and has complex boundaries, and the existing technology lacks a method for quickly and accurately calculating the amount of reinforcement work. Summary of the Invention

[0005] The purpose of this invention is to address the problem of low design efficiency caused by the lack of collaborative design of multiple types of anchors on a three-dimensional slope reinforcement surface in existing technologies. The invention designs a method to project a three-dimensional irregular slope onto a two-dimensional plane through topological relationships for anchor placement, while setting anchor placement rules to achieve efficient, rapid, and compatible placement of various reinforcement combination schemes on irregular geological bodies. This allows for quick and accurate calculation of reinforcement work volume, effectively improving design efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a method for designing anchors for irregular boundary slopes based on topological relationships, comprising the following steps:

[0007] S1. Determine the anchorage area and, based on computer graphics, establish a two-dimensional plane corresponding to the three-dimensional model of the anchorage area; S2. Define the anchorage arrangement rules based on topological relationships.

[0008] S3. Based on the anchor arrangement rules and the two-dimensional plane, the anchor arrangement area is divided to obtain the division result;

[0009] S4. Based on the division results, arrange the anchors and update the spatial topology of the anchor locations and related information.

[0010] Preferably, step S1 includes the following steps:

[0011] S11. Import a 3D model containing true 3D coordinates, project it as a 2D plane, and label it with a 2D coordinate system;

[0012] S12. Input coordinate points along the slope line of the anchorage area using a two-dimensional coordinate system and project them into the three-dimensional model to obtain the three-dimensional coordinates of the corresponding input coordinate points.

[0013] Preferably, the anchor arrangement rules include a first arrangement rule and a second arrangement rule.

[0014] Preferably, the first arrangement rule includes establishing a specific priority order, minimum arrangement interval, and row spacing for the anchors;

[0015] In the anchoring arrangement area, the anchors are arranged in a dot matrix manner, following the minimum arrangement interval, row spacing and priority order; when different anchors overlap, the low priority anchors are automatically eliminated to ensure that only one anchor is retained in each grid area.

[0016] Preferably, the second arrangement rule includes statistical analysis of the anchorage work volume through soft deletion.

[0017] Preferably, the soft deletion includes defining low-priority, invalid anchors as 0, and valid anchors effectively arranged in the anchoring arrangement area as 1; when calculating the anchoring quantity, if the anchor is 1, it is included in the anchoring quantity; if the anchor is 0, it is not included in the anchoring quantity.

[0018] Preferably, the design records of low-priority, invalid anchors are hidden during the query through classification and filtering, while retaining the design records.

[0019] Preferably, the anchor placement area is divided into grid surfaces according to the minimum arrangement interval and row spacing of the anchors, so that the anchor placement plane becomes a two-dimensional grid surface, and the anchor placement area is divided into several two-dimensional grids.

[0020] Preferably, when any anchor is inserted into the two-dimensional grid, the anchoring quantity is refreshed, and the spatial topology of the anchor location and related anchor information are updated.

[0021] Preferably, the anchors are designed with different combinations of anchors based on a material library and a reinforcement design scheme; the material library includes steel strands, structural steel, concrete, and reinforcing bars; the anchors include reinforcing bar frames, reinforcing bar ribs, anchor rods, anchor cables, anchor piles, shotcrete layer, cast-in-place layer, reinforcing mesh, and drainage holes; the reinforcement design scheme is designed based on the applicable scope of the anchors, anchor design specifications and standards, and expert experience.

[0022] The beneficial effects of this invention are:

[0023] 1. This scheme projects the three-dimensional irregular slope onto a two-dimensional plane through topological relationships to arrange anchors. At the same time, it sets anchor arrangement rules to achieve efficient, fast, and compatible arrangement of various reinforcement combination schemes on irregular geological bodies, thereby quickly and accurately calculating the reinforcement engineering quantity and effectively improving design efficiency.

[0024] 2. This solution projects the data onto a two-dimensional plane and marks it with a two-dimensional coordinate system. This allows for switching between two-dimensional and three-dimensional views of the ideal anchorage area on regular and irregular geological bodies. The two-dimensional view provides a clearer planar image, while the three-dimensional view offers a more intuitive stereoscopic effect. Switching between these views enhances the model's visual appeal and significantly improves work efficiency when dealing with complex models, thus effectively increasing design efficiency. By inputting coordinate points in a two-dimensional coordinate system and projecting them onto the three-dimensional model, the three-dimensional coordinates of the corresponding input points are obtained. This allows the anchors placed on the two-dimensional grid surface to be projected along the plumb line to the actual anchorage area, avoiding the errors and uncertainties of manually placing anchors in three-dimensional space.

[0025] 3. By setting clear rules for anchor placement, this solution allows engineers to determine the location and quantity of anchors more quickly, thereby improving work efficiency, reducing unnecessary waste, and lowering project costs.

[0026] 4. This scheme establishes a first arrangement rule to define the specific priority order, minimum arrangement interval, and row spacing of anchors, ensuring that only one anchor is retained in each grid area. This ensures that all relevant anchors are arranged in accordance with unified standards and specifications, thereby improving the standardization and consistency of the entire project.

[0027] 5. This solution provides a more flexible and controllable data management method by setting a second layout rule and using soft deletion to count the anchoring project quantity; it can easily track, recover and manage the soft-deleted data, improving the efficiency and accuracy of data management.

[0028] 6. This scheme defines statistical rules for anchorage quantities, which facilitates the subsequent statistical organization of relevant information on anchorage components, thereby effectively improving design and work efficiency.

[0029] 7. This solution uses soft deletion to calculate the anchoring project quantity, without actually deleting records from the database. Instead, these records are filtered out during the query using specific marking methods. All data still exists in the database, ensuring data integrity. Furthermore, since the soft-deleted data still exists in the database, it can be restored at any time, ensuring the flexibility of data use.

[0030] 8. This scheme ensures that each anchor is arranged according to the specified requirements by dividing the grid according to the minimum arrangement interval and row spacing, which improves the accuracy of the arrangement. Arranging anchors according to the grid surface can greatly improve the efficiency of the arrangement and avoid repetition and unnecessary arrangement.

[0031] 9. This solution ensures the accuracy of anchorage quantities by updating and refreshing anchorage-related data in real time. This is crucial for project budgeting and cost control. Furthermore, the real-time update and refresh technology makes anchorage quantity calculations faster and more efficient, improving work efficiency.

[0032] 10. By using a material library and designing reinforcement schemes, this solution ensures that all anchor combinations conform to unified standards and specifications, improving the degree of standardization. It also allows for rapid comparison and optimization of different anchor combinations, resulting in better engineering outcomes. Furthermore, it enables the rapid design and generation of different anchor combinations, improving design efficiency. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only one preferred embodiment of this invention and are only used to explain this invention. They do not limit the scope of protection of this invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0039] Example 1: As Figure 1 As shown, an anchorage design method for irregular boundary slopes based on topological relationships is presented.

[0040] S1. Determine the anchorage area and, based on computer graphics, establish a two-dimensional plane corresponding to the three-dimensional model of the anchorage area.

[0041] Specifically, S1 includes the following steps:

[0042] S11. Import a 3D model containing true 3D coordinates, project it as a 2D plane, and label it with a 2D coordinate system;

[0043] S12. Input coordinate points along the slope line of the anchorage area using a two-dimensional coordinate system and project them into the three-dimensional model to obtain the three-dimensional coordinates of the corresponding input coordinate points.

[0044] In this embodiment, the ideal anchoring area is projected onto a two-dimensional plane and marked with a two-dimensional coordinate system. This allows for switching between two-dimensional and three-dimensional views on regular and irregular geological bodies. The two-dimensional view provides a clearer planar image, while the three-dimensional view provides a more intuitive stereoscopic effect. Switching between the two-dimensional and three-dimensional views enhances the visual effect of the model and significantly improves work efficiency when dealing with complex models, thus effectively improving design efficiency. By inputting coordinate points in a two-dimensional coordinate system and projecting them onto the three-dimensional model, the three-dimensional coordinates of the corresponding input coordinate points are obtained. This allows the anchors arranged on the two-dimensional grid surface to be projected along the plumb line to the actual anchoring area, avoiding the errors and uncertainties of manually arranging anchors in three-dimensional space.

[0045] Understandably, in order to determine a reasonable anchorage area on the slope, computer graphics principles are used to import a three-dimensional model containing true three-dimensional coordinates into the graphics window of the electronic screen, project it as a two-dimensional plane, and mark it on the screen with a two-dimensional coordinate system, thereby realizing the switching between two-dimensional and three-dimensional modes of the ideal reinforcement area on regular and irregular geological bodies.

[0046] The two-dimensional plane formed by the above projection is a strictly closed two-dimensional region. It is based on the two-dimensional and three-dimensional co-point tangent closure of three-dimensional regular and irregular geological bodies to generate a two-dimensional geological profile. It can be directly converted into a two-dimensional plane in the three-dimensional model design software platform and used directly for reinforcement design. It can also be converted back into a three-dimensional model.

[0047] Two-dimensional tangent closure utilizes the tangent relationships between irregular line segments in a two-dimensional plane formed by projection and the tangent relationships between the plane boundaries to form a closed loop, thus forming a strictly closed two-dimensional region. Three-dimensional concurrent tangent closure refers to the fact that when three-dimensional irregular spatial surfaces intersect each other, they not only share the same intersection line, but also share the same node on the intersection line. The two-dimensional and three-dimensional sectioning and tangent closure algorithms adopt discrete mathematics theory and topological methods.

[0048] When performing digital design for geotechnical engineering reinforcement, including anchors (anchor rods, anchor cables, anchor piles, piles, drainage holes, etc.), coordinate points are input along the slope line in a two-dimensional coordinate system on an electronic screen. These points are then projected onto a three-dimensional model to obtain the corresponding three-dimensional coordinates. This allows the placement of anchors to achieve a conversion effect from two-dimensional input to three-dimensional recording. As a result, anchors placed on a two-dimensional grid surface can be projected along the plumb line to the actual anchor placement area, solving the anchor placement problem for both regular and irregular geological bodies.

[0049] S2. Define anchor placement rules based on topological relationships.

[0050] Specifically, the anchor placement rules include a first placement rule and a second placement rule.

[0051] In this embodiment, by setting clear rules for anchor placement, engineers can determine the location and quantity of anchors more quickly, thereby improving work efficiency, reducing unnecessary waste, and lowering project costs.

[0052] Specifically, the first arrangement rule includes establishing a specific priority order, minimum arrangement interval, and row spacing for the anchors; in the anchoring arrangement area, the anchors are arranged in a dot matrix manner, following the minimum arrangement interval, row spacing, and priority order; when different anchors overlap, the low-priority anchors are automatically eliminated to ensure that only one anchor is retained in each grid area.

[0053] In this embodiment, by setting a first arrangement rule, a specific priority order, minimum arrangement interval, and row spacing of the anchors are established, ensuring that only one anchor is retained in each grid area. This ensures that all relevant anchors are arranged in accordance with unified standards and specifications, thereby improving the standardization and consistency of the entire project.

[0054] Understandably, specific priority orders, minimum arrangement intervals, and row spacing are established for the arrangement of various types of anchors. The anchors are arranged on the two-dimensional grid surface in a dot matrix arrangement (cloverleaf or parallel alignment). When multiple anchors in the combined scheme are arranged on the two-dimensional grid surface, each specific anchor is arranged according to a specific arrangement interval, row spacing, and priority order. When multiple anchors are superimposed in the same grid area, anchors with lower priority are automatically eliminated according to the pre-set anchor priority order, ensuring that only one anchor is retained in a grid area in the end.

[0055] Specifically, the second arrangement rule includes statistical analysis of the anchoring work volume through soft deletion.

[0056] In this embodiment, by setting a second arrangement rule, soft deletion is used to statistically analyze the anchoring work volume, providing a more flexible and controllable data management method; the soft-deleted data can be easily tracked, recovered, and managed, improving the efficiency and accuracy of data management.

[0057] Specifically, the soft deletion includes defining low-priority, invalid anchors as 0, and valid anchors effectively arranged in the anchoring arrangement area as 1; when calculating the anchoring quantity, if the anchor is 1, it is included in the anchoring quantity; if the anchor is 0, it is not included in the anchoring quantity.

[0058] In this embodiment, by defining statistical rules for anchorage quantities, it is easier to collect and organize relevant information about anchorages in the future, thereby effectively improving design efficiency and work efficiency.

[0059] Specifically, the design records of low-priority, invalid anchors are hidden during the query through classification and filtering, while the design records are retained.

[0060] In this embodiment, the anchoring project quantity is statistically analyzed using soft deletion. This does not actually delete the records from the database. Instead, these records are filtered out during the query using a specific marking method. All data still exists in the database, ensuring data integrity. Furthermore, since the soft-deleted data still exists in the database, it can be restored at any time, ensuring the flexibility of data use.

[0061] Understandably, to facilitate subsequent statistics on anchoring work, invalid anchors with low priority and outside the reinforcement grid boundary are defined as "0" through "soft deletion," while valid anchors effectively placed in the reinforcement area are defined as "1." This deletion method does not completely remove invalid anchor records from the database, but rather filters out invalid anchor records during the query through a special classification method. Although they are not displayed in the reinforcement area, they still exist in the database.

[0062] S3. Based on the anchor arrangement rules and the two-dimensional plane, the anchor arrangement area is divided to obtain the division result.

[0063] Specifically, the anchor placement area is divided into grid surfaces according to the minimum arrangement interval and row spacing of the anchors, so that the anchor placement plane becomes a two-dimensional grid surface, and the anchor placement area is divided into several two-dimensional grids.

[0064] In this embodiment, by dividing the grid according to the minimum arrangement interval and row spacing, it can be ensured that each anchor is arranged according to the specified requirements, which improves the accuracy of the arrangement. Arranging the anchors according to the grid surface can greatly improve the efficiency of the arrangement and avoid repetition and unnecessary arrangement.

[0065] Understandably, dividing the anchor placement area into grid surfaces according to the minimum spacing and row spacing of the anchors creates a two-dimensional grid surface. Due to the unevenness of irregular geological surfaces, in order to completely cover the anchor placement area, the coverage area of ​​the two-dimensional grid surface will be a regular quadrilateral, exceeding the size of the reinforcement area. The row and column spacing of the two-dimensional grid is determined according to the minimum spacing and row spacing among various anchor types, strictly limiting only one anchor to a single grid area. This improves the efficiency of anchor placement while addressing the drawbacks of overlapping anchors in the same area.

[0066] Since the coverage area of ​​the regular quadrilateral two-dimensional mesh surface will exceed the area where the reinforcement is placed, and the reinforcement area will have a certain degree of intersection with the mesh surface, in order to solve the problem of reasonable placement of anchors at the boundary between the mesh surface and the reinforcement area, it is stipulated that when the centroid of the two-dimensional mesh is not within the boundary of the reinforcement area, no anchors are allowed to be placed in the mesh area.

[0067] Topological relationships exist between two-dimensional grids and closed curves. The former provides a general technique for multiple orders, multiple relationships, and non-repeating arrangements; the latter applies this logic to arbitrary slopes, eliminating anchors that fall outside the slope boundary.

[0068] The aforementioned general techniques of multiple ordering, multiple relationships, and non-repetitive arrangement correspond to priority ordering, minimum arrangement intervals, and row spacing. Multiple ordering indicates that different types of anchors have different priority orders. Anchors are assigned priority orderings before arrangement. Within the same grid, higher-priority anchors dominate and "squeeze out" lower-priority anchors. Multiple relationships indicate that there is a minimum basic multiple relationship between the arrangement intervals and row spacing of anchors with different priority orders. When the minimum row spacing of the highest priority anchor is 8m, the row spacing of lower priority anchors can only be 1m, 2m, or 4m, with a minimum row spacing of 1m being the minimum basic multiple.

[0069] Specifically, when any anchor is inserted into the two-dimensional grid, the anchoring quantity is refreshed, and the spatial topology of the anchor location and related anchor information are updated.

[0070] In this embodiment, by updating and refreshing the anchorage-related data in real time, the accuracy of the anchorage quantity can be ensured. This is crucial for project budgeting and cost control. Furthermore, the real-time update and refresh technology makes anchorage quantity calculation faster and more efficient, improving work efficiency.

[0071] Understandably, the support and reinforcement design is based on the method of inserting anchors on a two-dimensional grid surface. When any anchor is inserted into a node on the grid surface to be reinforced, the two-dimensional grid surface values ​​are refreshed, the spatial topology of the anchor position and the type and parameter information of the anchor are updated, and the spatial anchor position topology is updated to complete the multi-anchor support and reinforcement design within a specified slope area.

[0072] Specifically, the anchors are designed with different combinations of anchors through a material library and a reinforcement design scheme; the material library includes steel strands, structural steel, concrete, and reinforcing bars; the anchors include reinforcing bar frames, reinforcing bar ribs, anchor rods, anchor cables, anchor piles, shotcrete layer, cast-in-place layer, reinforcing mesh, and drainage holes; the reinforcement design scheme is designed based on the applicable scope of the anchors, anchor design specifications and standards, and expert experience.

[0073] In this embodiment, by using a material library and designing reinforcement schemes, it can be ensured that all anchor combinations conform to unified standards and specifications, thereby improving the degree of standardization. Different anchor combinations can be quickly compared and optimized to achieve better engineering results. Furthermore, different anchor combinations can be designed and generated quickly, improving design efficiency.

[0074] Understandably, support reinforcement design involves creating anchor combinations tailored to different projects using a material library and designed reinforcement schemes. The material library encompasses various types of steel strands, structural steel, concrete, and reinforcing bars; anchors include reinforcing bar frames, reinforcing ribs, anchor bolts, anchor cables, anchor piles, shotcrete layers, cast-in-place layers, reinforcing mesh, and drainage holes. The designed reinforcement schemes, based on the applicable scope of the anchors, relevant design specifications / standards, established design methods, and expert experience, include several pre-configured general reinforcement schemes. Alternatively, anchors with appropriate parameters and different special reinforcement schemes can be configured according to the reinforcement design requirements.

[0075] The design and reinforcement schemes can be divided into conventional reinforcement schemes and special reinforcement schemes. The conventional reinforcement schemes built into the system include a material library and an anchor library. The material library includes four basic materials: steel bars, concrete, steel strands, and structural steel. The anchor library includes steel ribs, anchor rods, anchor cables, anchor piles, shotcrete layers, cast-in-place layers, and steel mesh.

[0076] After completing the conventional reinforcement scheme, special reinforcement schemes can be directly applied to areas with specific layouts, forming anchor combinations tailored to different engineering parts. Slope anchor placement can be done on a regional basis, with one design reinforcement scheme per region. The anchors and parameters included in each design reinforcement scheme are defined according to the scheme's specifications. The system pre-configures several common conventional reinforcement schemes, and can also configure anchors with appropriate parameters and different special reinforcement schemes based on the applicable scope of the anchors, relevant design specifications and standards, established design methods, and expert experience. The designers undertaking the specific tasks then select the most suitable scheme from the candidate schemes for the specific engineering requirements, followed by review and optimization.

[0077] This embodiment provides a detailed explanation (principle, etc.) of the effects, purpose, or a certain feature of the embodiment, and expands on the content.

[0078] Furthermore, specifically as follows:

[0079] S1. In order to determine a reasonable anchorage arrangement area on the slope, the principle of computer graphics is adopted to import a three-dimensional model containing true three-dimensional coordinates into the graphics window of the electronic screen, and then project it as a two-dimensional plane, which is marked on the screen using a two-dimensional coordinate system.

[0080] Input coordinate points along the slope line in a two-dimensional coordinate system on the electronic screen, project the points onto the three-dimensional model to obtain the corresponding three-dimensional coordinates, so that the arrangement of anchors can achieve the conversion effect of two-dimensional input and three-dimensional recording, so that the anchors arranged on the two-dimensional plane can be projected along the plumb line to the actual anchor arrangement area.

[0081] S2. Establish specific priority order, minimum arrangement interval and row spacing for the arrangement of various types of anchors. Arrange the anchors on the two-dimensional grid surface in a dot matrix arrangement (cloverleaf or parallel alignment). Each specific anchor is arranged according to a specific arrangement interval, row spacing and priority order. When multiple anchors are arranged in the same grid area, the anchors with lower priority are automatically eliminated according to the pre-set anchor priority order. Only one anchor is retained in a grid area.

[0082] To facilitate subsequent statistics on anchoring work volume, invalid anchors with low priority and outside the reinforcement grid boundary are defined as "0" through "soft deletion", while valid anchors effectively placed in the reinforcement area are defined as "1".

[0083] S3. Divide the anchor placement area into a grid surface according to the minimum spacing and row spacing of the anchors, making the anchor placement plane a two-dimensional grid surface. The row and column spacing of the two-dimensional grid is determined according to the minimum spacing and row spacing among various anchor types, such as... Figure 2 As shown, only one anchor is allowed within a single grid area.

[0084] S4. The support and reinforcement design is based on a two-dimensional grid surface to achieve the insertion of anchors, such as... Figure 3 As shown, when any anchor is inserted into a node on the grid surface to be reinforced, the two-dimensional grid surface value is refreshed, the spatial topology of the anchor position and the type and parameter information of the anchor are updated, realizing the update of the spatial anchor position topology and completing the multi-anchor support and reinforcement design within a specified slope area.

[0085] After the reinforcement design is completed, the quantities of reinforcement and drainage works are output according to the built-in output instructions of the design software, such as... Figure 4 As shown, the statistical results of the surface reinforcement, walkway protection, and drainage engineering quantities are obtained.

[0086] The above-described specific embodiments are preferred embodiments of the present invention and are not intended to limit the specific scope of the present invention. The scope of the present invention includes, but is not limited to, these specific embodiments. All equivalent changes made in accordance with the shape, structure, and method of the present invention are within the protection scope of the present invention.
